Black Box sp390a-r2

I do this using a black box SP390A-R2 from black box. It is a usb optical isolator for a 485 network 2 wire or 4 wire. XP will configure it automatically for a com port. I have to go into the device manager and set the device to com 2 to work with xpsi. You also have to make sure that nothing else is on comm 2. In psi you need to setup the connection for psi host and the baud rate to 9600 or 19.2. The baud rate will depend on the setup of the microzones so sometimes you just have to try them out to see what works best. There are some switches on the black box that will all need to be in the on position. for the rj-11 connector the RDA- on the box will need to go to pin 4 on a 6 pin RJ-11 and pin and pin 3 on a 4 pin RJ-11. The TBA+ goes to pin 3 on a 6 and 2 on a 4 pin. I will warn you that this does not always work the best especially if your use to an older pc. A lot of the times I have to remove one leg of the ASD trunk on the microzone to connect to it especially if there is a GCM on the network. You can also unhook the GCM from the network and get it to work too. The node list doesn't always work either, but what do you do this technology is from the late 80's and everythign else is light years ahead of it. I hope this helps you and feel free to contact me if you have any questions.

have had really good luck with this working on WIN7 with the newest 4.0 XPSI. We also will use this inside a virtual machine running XP without any problems. We like the virtual machines because we can set one machine up and then copy it to all the technicians computers.

Thanks guys! I just ordered one and have my MZ2 on the way for some desktop programming before I try to migrate everything into the Niagara world. I used a Smartwaretech program to perform a GCM dump so now I have all the GCM info in Viso files. How do I tell from the dump files if all programming is in the GCM or in the MZ's and MFLO's? Still trying to figure out if I change over the system to a JACE how much programming needs to be done. I would guess that the field controllers would be set up to run stand alone and then only communicate back to the GCM their current status? I really appreciate the help from everyone as I'm really learning Niagara, Signal and XPSI all at the same time!

The information passing between a MZ2 and GCM will happen through the EMS block. You have a total of 8 AI and 8 DI to be able to pass from the GCM to the MZ. If there is logic in the GCM you can trace it back starting at the EMS block and going back from there. Ususally we see things like set points, schedule, global OA temp, and reset schedules in the GCM and them passed down to the MZ. These ems block also have to be used to pass from one MZ to another. the point would have to go from MZ up to GCM back down to another MZ. In the MZ controller there will also be a EMS block that you can put default parameters in for a communications failure. The MFLO's are pretty much a canned application. You are just using the GCM to pass things like set points and schedule information. Also the GCM becomes the place to read all the information to display on some sort of graphical package. We have done a ton of these integrations with a ASD driver from infocon. it works great. We are for hire if you need some help.
